Abstract:

The instability of coal and rock mass is the direct cause of mine disasters. It has become an inevitable development trend to monitor and warn coal and rock mass with long period and high efficiency. The infrared thermography of transportation roadway in Hongliu Coal mine I010401 working face and I020308 working face in the observation period is studied The variation characteristics of average infrared radiation temperature (AIRT) and differential infrared radiation temperature (VSMIT) were obtained, and the VSMIT judgment threshold of the transportation lane of hongliu Coal mine I010401 working face and I020308 working face was obtained The research results show that the application of infrared radiation monitoring technology in field monitoring is feasible, which can provide reference for the application of infrared radiation monitoring technology in the stability monitoring of surrounding rock in mine.
